SUPPLEMENTARY COOLING HOOD FOR MOTORS.

Application filed. May 3, 1922.

To all whom it may concern Be it known that I, Vroron W. PAGE, a citizen of the United States, and a resident of the city of New York, Kew Gardens, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Supplementary Cooling Hood for Motors, of which the following is a full, clear, and exact description.

The present invention relates to new and useful improvements in internal combustion motors, and it pertains more particularly to a means for cooling internal combustion motors mounted in motor vehicles.

It is one of the primary objects of the invention to provide a supplementary hood adapted to be placed beneath the ordinary hood, said supplementary hood being adapted to enclose the motor cylinders.

It is a further object of the invention to provide a hood which will prevent dissipation of the air into the upper portion of the engine compartment, said hood causing the air to pass in the presence of all of the cylinders of the motor.

It is a further object of the invention to provide an air funnel which in addition to concentrating the air, serves as a fan guard and also as a means for protecting the electrical apparatus, namely, the magneto and generator when positioned at the front of the motor, from the weather.

It is a further object of the invention to construct the supplementary hood so that the air speed will be substantially constant throughout the engine compartment in order that the rear cylinders of the motor will be effectively cooled.

It is a further object of the invention to construct the supplementary hood so that the same comprises hinged sections which may be lifted or raised in order that the several working parts of the motor will be readily accessible.

lVith the above and other objects in view, reference is had to the accompanying drawings, in which Figure 1 is a longitudinal sectional view of the motor compartment of the motor vehicle showing the location and construction of the supplementary air hood.

Fig. 2 is a vertical sectional view taken on the line 2-2 of Figure 1.

In the present instance the invention is illustrated as applied to a motor of the aircooled type and in the drawings the refer- Serial No. 558,229.

ence character 5 designates a radiator shell 1n imitation of a radiator and the front portion of the radiator shell is provided with a grille 6 to complete the imitation of a water radiator. The radiator shell is formed with a ledge or shoulder 7, and engaging over said ledge or shoulder 7 isa funnel-shaped member 8 having a circular flange 9. As more clearly shown in Fig. 1, the lower portion of this funnel-shaped member 8 is provided with a downwardly curved wall 10, which extends to the lower wall of the radiator shell 5. The reference character 11 designates a fan or air impeller and said fan or air impeller is mounted so that its blades operate within the flange 9 of the funnelshaped member 8. p

The reference character 12 designates the dashboard of the vehicle or the rear wall of the motor compartment and secured to the front base of said dashboard 12 is a supporting ledge 13.

The supplementary hood comprises a pair of hingedly connected members 1 1 and 15, said members being hingedly connected together by the hinged oint 16, and said members are adapted to overlap the flange 9 of the funnel-shaped member 8. Each of these hinged members 14 and 15 is provided on its forward end with a hook-like member 18 adapted to be engaged by means of a catch 19, said catch 19 being carried by the flange 9 and adapted to engage the hook member 18 to maintain the sections 14 and 15 in closed position. At the rear of the supplementary hood latches 20 are employed to maintain the hood in position with respect to the hood supporting ledge 13.

The device operates in the following manner:

Air drawn in through the radiator shell 5 by the fan 11 will be projected rearwardly through the supplemental hood member, and owing to the inclined position of the top wall of the supplemental hood the velocity or air speed will be maintained uniform throughout the entire length of the supplementary hood. Furthermore by employing a supplemental hood, a dissipation of the air in the upper portion of the motor compartment is prevented and the entire volume of air set in motion by the fan is caused to pass in the presence of the motor cylinders to cool the same.

It will also be noted that owing to the forwardly and downwardly curved wall 10, the

generator and the magneto, which are designated by the reference characters 20 and 21 and which are ordinarily positioned at the front of the engine compartment, are protected from the elements since Water and the like entering the radiator shell is prevented from coming in contact With said electrical apparatus.

What is claimed is:

1. In combination with the engine conipartment of a motor vehicle having a radiator forming its front wall, a supplemental motor hood, said hood comprising a forwardly disposed flared member embracing a portion of the radiator, said flared portion having a rearwardly disposed flange, a motorcovering hood. supported at its forward end on said flange, and means carried by the rear Wall of the engine compartment for sup porting the rear end of the motor-covering hood,v

2. In combination with the engine compartment of a motor vehicle having a radiator forming the front Wall thereof, a supplemental motor hood comprising a flared member adapted to embrace the radiator, arearwardly projecting flange formed on said flared member, and a plurality of hinged members forming a supplemental motor hood, said hinged members being supported at their forward ends on the reai'wardly-dis posed flanges of the flared members.
